“…48 Increased antibody response was observed in tilapia 49 and synthesis of Heat Shock Protein 70, a signal of immune response, was observed in brine shrimp. 48 Recent research indicates that ingestion of PHB may improve survival of P. monodon against White Spot Syndrome Virus, 138 supporting the hypothesis that PHB activates the innate immune system, providing nonspecific protection against an array of pathogens. 105 The input energy for MOB and HOB is a theoretical thermodynamic minimum equal to the − TΔ r S x term illustrated in Figure 3.…”

Meeting global food needs in the face of climate change and resource limitation requires innovative approaches to food production. Here, we explore incorporation of new dark food chains into human food systems, drawing inspiration from natural ecosystems, the history of single cell protein, and opportunities for new food production through wastewater treatment, microbial protein production, and aquaculture. The envisioned dark food chains rely upon chemoautotrophy in lieu of photosynthesis, with primary production based upon assimilation of CH4 and CO2 by methane- and hydrogen-oxidizing bacteria. The stoichiometry, kinetics, and thermodynamics of these bacteria are evaluated, and opportunities for recycling of carbon, nitrogen, and water are explored. Because these processes do not require light delivery, high volumetric productivities are possible; because they are exothermic, heat is available for downstream protein processing; because the feedstock gases are cheap, existing pipeline infrastructure could facilitate low-cost energy-efficient delivery in urban environments. Potential life-cycle benefits include: a protein alternative to fishmeal; partial decoupling of animal feed from human food; climate change mitigation due to decreased land use for agriculture; efficient local cycling of carbon and nutrients that offsets the need for energy-intensive fertilizers; and production of high value products, such as the prebiotic polyhydroxybutyrate.

“…WSSV causes heavy damage to the shrimp aquaculture. Monica et al [ 84 ] studied the immunomodulatory role of PHB/BS against WSSV infection in shrimps. Increased levels of hemocytes were observed in both BS (28 ± 2 × 10 4 cells)/PHB (26 ± 2 × 10⁴ cells) administered groups.…”

“…Increased levels of hemocytes were observed in both BS (28 ± 2 × 10 4 cells)/PHB (26 ± 2 × 10⁴ cells) administered groups. Supplementation with 2% PHB or BS increased the survival rate of WSSV infected P. monodon which might be associated with observed over expression or down regulation of proteins involved in boosting the immune responses [ 84 ]. Various levels of dietary phospholipids or cholesterol strongly affected the expression of several immune-related genes in juvenile freshwater cultured Litopenaeus vannamei [ 85 ].…”

Microbial surfactants (biosurfactants) are a broad category of surface-active biomolecules with multifunctional properties. They self-assemble in aqueous solutions and are adsorbed on various interfaces, causing a decrease in surface tension, as well as interfacial tension, solubilization of hydrophobic compounds, and low critical micellization concentrations. Microbial biosurfactants have been investigated and applied in several fields, including bioremediation, biodegradation, food industry, and cosmetics. Biosurfactants also exhibit anti-microbial, anti-biofilm, anti-cancer, anti-inflammatory, wound healing, and immunomodulatory activities. Recently, it has been reported that biosurfactants can increase the immune responses and disease resistance of fish. Among various microbial surfactants, lipopeptides, glycolipids, and phospholipids are predominantly investigated. This review presents the various immunological activities of biosurfactants, mainly glycolipids and lipopeptides. The applications of biosurfactants in aquaculture, as well as their immunomodulatory activities, that make them novel therapeutic candidates have been also discussed in this review.

“…PHB could also stimulate the immune system of crustacea in the early stage, upregulate the expression of antimicrobial peptides, and modulate intestinal health of crustaceas and fish by adjusting intestine microbiota and activating mTOR signaling (Sui et al, 2012;Duan et al, 2017;Qiao et al, 2019). In addition, dietary PHB supplementation and PHB existing in water can enhance the resistance of shrimp against Vibrio and white spot syndrome virus (WSSV) infection (Baruah et al, 2008(Baruah et al, , 2015Deng et al, 2014;Monica et al, 2017). Our previous research studies demonstrated that: (1) gibel carp can uptake bioflocs (Zhang et al, 2018); (2) PHB is one of major bioactive compounds in bioflocs, and PHB can enhance the disease resistance of gibel carp against CyHV-2 infection (Qiao et al, 2020).…”

Poly-β-hydroxybutyrate (PHB) can promote growth and enhance immunity of aquatic animals such as gibel carp, Carassius auratus gibelio. However, the optimal dietary supplementation level and feeding duration for gibel carp are still unclear. In this study, effects of various PHB supplementation levels on gibel carp growth performance, digestive enzyme activities, immune function, disease resistance, and intestinal mucosal barrier were evaluated. Six experimental diets differing in PHB levels were formulated, that is, 0% (P0 as control), 0.5% (P0.5), 1% (P1), 2% (P2), 4% (P4), and 8% (P8). Results indicated that PHB promoted fish growth performance significantly (p < 0.05). Compared to control group P0, the intestinal lipase, protease, and amylase activities in group P4 were significantly increased after 30 days (p < 0.05). Meanwhile, dietary PHB supplementation at 4% level for 30 days and 0.5% for 60 days upregulated the mRNA expression of immune-related
